Have you had your thyroid checked? It is quite common to have thyroid issues with celiac and if you are eating that much and not gaining weight you could have hyperthyroidism or have some other condition that is preventing you from gaining weight.

I am having the same issue! Before I discovered my intolerance for wheat/gluten I was hovering around 170lbs. After getting sick and losing 15-20lbs within the span of 1.5-2 months (prior switching to gluten free), I have been incapable of putting weight back on. I have increased my protein intake in an attempt to put on weight along with helping to build muscle and I've also stopped watching my sugar/carb/calorie intake. I've been purposely letting myself eat worse in hopes that it will help put on any kind of weight! Nothing seems to be working!! I hope you have more luck with it than I and would be interested to hear any other tips / success stories!
